Using spectroscopy (a process where researchers can determine the contents of a substance by seeing the way it refracts light), scientists found a number of heavy elements, including iron, magnesium and silicon inside the asteroid. Even more interestingly, the researchers also found, “…a huge excess of oxygen—an amount, they say, that indicates the asteroid…was originally composed of 26 percent water. That’s pretty wet—Earth, by contrast, is only 0.02 percent water.”

*NOTE: 70% of Earth’s surface is covered in water. However, only 0.02% of Earth’s mass is water.
